    need to crack a PW in PHPBB via myphpadmin

    Hey all,

    Not sure if anyone can help me, i forgot a password in phpbb and instead of screwing with anything i was wondering if there is a way to decode the cripted password that is listed in myphpadmin.
    which is e5a86e2d3dc4264c41583f3cb5ff8dba

    No. Those hashes are one way. Just reset it to a known password.

    Something tells me that isnt his own MD5sum and his story isnt quite truthful

    If thats the case, all is *perhaps* not lost, but its going to cost you a lot of CPU time. MD5 hashes are crackable by either brute-forcing it or if you are very lucky, finding a collision value that produces the same hash value.

    Google for 'md5 collision table'. Someone out there has a site where you can submit a hash and it will be searched against a huge database of known hashes.

    It might be helpful if you know the forum's salt (if it uses one).

    I think in this case that bruteforcing is probably your best bet. In the interest of the public, I will not link you directly to such utilities, but a 5 minute googling should be illuminating.

    couldn't you create another instance of phpbb using your hashed password, then replace this hash with the one you showed above and then you can get in?

    unless you don't want the owner of the database to know the password has been changed ;-)

    If he already had database access, you would just change your password.

    Update your password too 4f4986dcc6b54a4e967585878498dfdc

    and then login with the password hostgeekz and reset it.

    Why don't you use the password recovery utility built into phpbb, just below login "I forgot my password link" Thats why it is there. If it is the Admin password, then why don't you look it up in the config file. However if your truly the admin, the pasword recovery utility would work.

    Maybe it was hacked? And they changed his email so he couldnt recover his pass? Or change it?

    If that was the case he could edit the sql file and change the email, which is not encrypted. Then click send me my password. The whole thing sounds fishy to me.

    Follow these steps to reset it,

    1. Register a new user in the phpbb and remember the password.

    2. Login to mysql using ssh

    3. Execute the follow query in mysql,

    select * from phpbb_users;

    4. Now in the last of that query's result you will find the username which you have registered and its password. For example we will assume his password is

    102087ef20bdb802b248d7182270dbbc

    5. Copy the password

    6. Now execute the following command in mysql,

    select * from phpbb_users limit 0,5;

    Here you can see the admin user's details with his password.

    7. Now execute the following command in mysql to reset his password,

    update phpbb_users set user_password = '102087ef20bdb802b248d7182270dbbc' where username = 'admin';

    So now the newly registered user's password is used for the admin user's password. In order to do this you need shell access, if you don't have contact your hosting support.
